2. Post and pay. Send the same JSON to POST /v1/posts. The server answers 402 Payment Required with the price; sign the USDC payment on Base and send it again. Many listings? Send {"listings": [ … ]} — up to 15 in one payment.
3. Keep the key. The reply has the page address, an edit key (shown once) and the expiry date. Edit or remove the listing with the key; renew it before it ends.
